Question 3954 Deck General

The correct answer is B) The vessel's trim will change. When a vessel enters shallow water, the water flowing under the vessel's keel will become restricted, causing the water pressure to increase. This increase in water pressure will result in a change in the vessel's trim, causing the bow or stern to rise or lower relative to the vessel's center of gravity. This trim change is a natural consequence of the vessel's interaction with the shallow water environment. The other answer choices are incorrect because: A) A change in list is more associated with stability issues, not specifically with shallow water entry. C) An increase in speed is not a necessary result of entering shallow water. D) Rudder effectiveness may change, but this is not the primary effect of entering shallow water.
